NHibernate 3 Beginner's Guide

By: Dr. Gabriel Nicolas Schenker, Aaron Cure

Overview of this book

<p>Ideally, we would want to persist the objects our application uses and produces AS IS, without having to first transform them in complex ways. NHibernate is a framework that provides us with an object-oriented access to a relational database without having to write SQL and with little or no database-specific data access code. Definitely, if you are a .NET developer, knowing more about NHibernate will simplify and reduce your efforts in developing .Net applications.<em>NHibernate 3 Beginner's Guide</em> introduces Nhibernate with step-by-step examples, and is the easiest way to learn about bridging the gap between object-oriented .NET applications and the relational database that stores the application's data. It is a beginner's guide to NHibernate that starts from scratch. Successive chapters build upon earlier concepts, while the sample code presents various ways to accomplish typical data access tasks.</p> <p><em>NHibernate 3 Beginner's Guide</em> examines all of the topics required to get a functional data access layer implemented while writing the least amount of code possible, presenting options along the way to handle particular edge cases or situations as they arise. The book begins with an introduction to NHIbernate 3 and then moves on to creating the development environment. Then it teaches you how to create a model, define a database schema, and map the model to the database then covers sessions and transactions. This is succeeded by testing, profiling, and configuration, validation of data and writing queries. Finally, we wrap up with notes on the common pitfalls that you should avoid.</p> <p>Once you complete reading the book, you will have gained the skills and knowledge to incorporate NHibernate into your own applications.</p>

Summary


We learned in this chapter what the minimal steps are that are needed to create a working application which uses NHibernate as an ORM framework, and is able to write data to and read data from a database.

Specifically, we covered:

  • What the prerequisites are and how we need to configure our system to be able to develop applications that use NHibernate 3

  • How we can define a model and map this model to the underlying database by using Fluent NHibernate

  • How to make NHibernate automatically create a database schema for us

  • How we create a session factory and how to use this factory to create sessions, which in turn are used to persist data to and retrieve the existing data from the database

Now that we've learned how we can use NHibernate in a real world application, we're ready to dig deeper into the details of the various steps we presented. In the next chapter, we start with the definition of the model.
